THE POWER OF INFORMATION INTEGRATION IN INDUSTRIALAUTOMATION ALLIED TO IEC 61850How to make industrial automation to be more efficient, using information to integrate Process andElectrical Automation systems based on IEC 61850 StandardAlan Fernandes Teixeira 1and Leandro Henrique Monaco 21Alan Fernandes Teixeira is application engineer of electrical automation at the mining segment on Process Automation division in ABB Brazil, and he’s graduated in Electrical Engineering – Electrotechnics on São Judas Tadeu University. 2Leandro Henrique Monaco is electrical automation engineering manager at the mining segment on Process Automation division in ABB Brazil, and he’s graduated in Electrical Engineering – Automation and Control and Master of Science in Systems Engineering by Polytechnic School of University of São Paulo.1 – IntroductionA substation automation system is basically composed of elements to protect equipment, to control switches, circuit breakers and transformers, as well as supervision and monitoring of the status from all involved equipment, respecting each equipment features and possible limitations.There are two typical scenarios when it comes to substation automation: the first relates to new plants, in which the designer can create a concept for the plant automation, define the best network and infrastructure topology, in order to mitigate the risks, get complete information of the electrical system and optimize the system implementation costs; but there is also the second scenario, where existing plants are in production (some for many years) and without dedicated infrastructure to electrical automation. In these plants it is common to find several automation systems for each substation, using usually PLCs, supervisory systems from various vendors with little or no information exchange because, as a rule, there isn’t a central system that manages all substations, making plant control and management to be much harder.In these days, it’s essential to have an automation system capable of integrating all available information into a single platform, regardless of the model chosen for a particular protection relay or the chosen protocol, and making information available anywhere in the plant so as to facilitate remote operation. Moreover, the possibility of integrating the substation automation system to the process control system enables a single database and complete plant management, both for operation and maintenance.Figure 1. Leandro Monaco and Alan Fernandes: "It’s essential to have an automation system capable of integrating all available information into a single platform".2 – Electrical Automation Integrated System2.1 IEC61850 standardWith the evolution of substation equipment, such as IEDs (Intelligent Electronic Devices) and digital meters, and with the advent of IEC 61850, the possibility of having the equipment integration from different vendors in a single system becomes reality. In the case of plants in production, such integration allows several substations with IEDs from different vendors to be grouped into a single system, because they all speak "the same language". This makes operation and maintenance of the electrical system to be easier, bringing information from the whole plant. This is called interoperability.IEC 61850 standard can be misunderstood as a communication protocol; however, it goes far beyond that. In order to standardize the complete communication concept in substation automation, the standard is based on three goals: interoperability; freedom of configuration and long-term stability. Interoperability is the ability for IEDs from different vendors to communicate with each other; freedom of configuration is the ability of each vendor to use different methods and philosophies in the internal programming of the logic performed by IEDs, as long as the data exchange between them obey the goal of interoperability, and concerns the freedom to allocate functions to one or more IEDs during the substation project by the engineering team; and long-term stability refers to the ability of communication protocols to remain updated in front of technological advances.For that, the way devices exchange data is standardized, using the concept of Logical Node. According to its definition, a Logical Node is "the smallest part of a function that exchanges data" (IEC 61850-SER ed1.0, 2010). Each substation function is broken into smaller parts, and data exchanged between each part is standardized, without affecting the inner operation of each part. This ensures interoperability and freedom of configuration.In order to allow information exchange between devices, two communication protocols are defined: one for communication between IED and supervisory system, called MMS; and another for fast communication between IEDs for interlocks and logic selectivity, called GOOSE. MMS protocol (Manufacturing Message Specification) is used for communication between IEDs and supervisory system based on client-server philosophy, i.e., the IED becomes a server for the information available in it and the supervisory system becomes a client for that information; it is used for supervision and operation information, being a non-critical time communication. GOOSE protocol (Generic Object Oriented Substation Events) is used to exchange the critical time information between IEDs inside network for protection, interlocking and logic selectivity purposes; this communication is based on MAC addresses, and allows the transmission of packets in the network as fast as 3 ms. GOOSE protocol is one of the great advantages of IEC 61850, reducing the amount of wiring between cubicles of a substation to perform logic selectivity schemes, greatly reducing installation and maintenance costs.All communication between the devices is over Ethernet network protocol, globally known in enterprise environments and now also in the industry ones. At this point, it’s important to notice the importance of network configuration on an industrial project. Today it is no longer possible to foresee an industrial scenario without communication possibilities offered by industrial networks. The need for information integration (achieved long ago in IT scenarios) becomes crucial in industrial scenarios, and will become increasingly essential in the near future.Figure 2 presents a generic topology that addresses the minimal concepts of an electrical automation project. One can see the substation equipment such as circuit breakers, switchgears etc., (given by iPASS Switchgear boxes) as well as measuring instruments like CTs and VTs (MUPX and MUPY boxes), physically connected to the protection and control IEDs (given by boxes Bay Controller, Prot X and Prot Y), which are connected to an Ethernet switch. The switches of each substation are part of a network that is connected to protocols gateways and to human-machine interface equipment (HMI). GPS devices are also commonly used to synchronize time on the IEDs in order to allow the sequence of events (SoE).Figure 2-Network Topology of the Automation System in IEC 61850.2.2 Advantages for the electrical systemAs the intelligence for protection and logic selectivity is distributed to the IEDs (which can now communicate with each other), the DCS can be in charge of power management and other logics that require a higher level system view. Some functions such as load shedding, generator control, turbine management, transformer tap control can be run on the DCS, and some controllers have GOOSE interface, achieving operating times faster than 10 ms, thus reducing selectivity adjust times, taking care of mechanical health of cabling, circuit breakers, switchgears and machines, without using hardwires.Another great advantage with the advent of IEC 61850: a trend of all equipment in the electrical system to suit the communication according to IEC 61850, which initially started only in IEDs. Today we already have digital meters, and soon CTs and VTs will emerge in the market with communication drivers, plus circuit breakers and switchgears, i.e., it will be possible to see the system more and more integrated, through a single standard of network connection and the electrical system itself.3 – Case study: Itabira integrated systemIn order to show how the information integration brought by the use of IEC 61850 concepts, especially interoperability, some features of a real system already implemented are here illustrated. This section is about the electrical automation integrated system of Itabira, the iron ore beneficiation plant located in the city of Itabira-MG, Brazil. In this system, six main substations were integrated into a single system, providing information ofhigh voltage equipment such as 230 kV and 69 kV up to medium voltage as 13.8 kV and 4.16 kV. The six substations are located in different places around the city, separated by distances up to 30 km from the central operating room. The IEDs are from two different vendors, due to the fact that substations retrofits were made at different periods and under different contracts.The supervisory system is from a third vendor, and it communicates with the IEDs via MMS protocol for system operation and supervision. Moreover, due to the large distance between the substations and the risk of losing communication, it was used a contingency operation solution in each substation, consisting of a human-machine interface touch screen panel and a controller with GOOSE interface, being able to receive data from and send commands to the IEDs, in order to ensure remote operation of circuit breakers and switches. This guarantees the main project concept: to keep the operator away from the electrical cubicle, and consequently from the electrical risk.Figure 3 illustrates the generic automation system topology used in Itabira. One can see how the two interfaces of the automation system to the IEDs, using both protocols proposed by IEC 61850.Figure 3. Automation System Network Topology, with two interfaces to IEC 61850 devices.Due to greater amount of information available in the IED network because of digital communication protocols (IEC 61850 network in Figure 3, for better understanding), besides the possibility of communication between IEDs from different vendors located in substations away from each other, it was possible to get an integration level of all the available information in the same system, so the electrical system operation is possible regardless of where the operator is. The information centralization through Ethernet networks also allowed creating a remote operating room, from where there is view of everything that’s happening in the system. Moreover, system maintenance also become easier because the IEDs can be parameterized and configured from anywhere with access to the automation system, and if it’s necessary to go to the failure spot, the technician will be able to get there with more details about what happened. So the three main project concepts were achieved: remote operation guaranteed; remote maintenance; and integration of information in a single system.4 – Electrical and Process automation integration on the same systemThe adoption of Ethernet-based systems makes open protocols to be used more often, creating more complete automation systems, thus optimizing costs and information availability on the entire plant.In the past, and in many plants in operation nowadays, there is still a strong separation between the electrical automation system, responsible for power management, and the process automation system, more focused on the production, in a way that there is little or no exchange of information between them. Today one can understand it’s an increasing trend to have a single system managing the entire plant, looking for both Process and Electrical automation with excellent performance and availability through a unique DCS system.Figure 4 presents a topology that can best show the new model.Figure 4. Integrated Topology for Process and Electrical Automation Systems, using IEC 61850.4.1 Advantages for the process control systemAmong the advantages that can be pointed from this integration, cost reduction is the first one, because servers, software and hardware are optimized. Besides that, indirect costs such as training and investment shared between areas. In addition, new features can be implemented from the combination of information.An example of this possibility is the adoption of medium voltage protection relays for motors control in IEC 61850, in which it’s possible to use all the benefits of GOOSE messages between IEDs without losing the interaction with process equipment, such as instrumentation, valves, and inverters.A real case for this functionality can be given by a conveyor that handles ore, steel or any other goods.Usually in these cases, big medium voltage motors are responsible for the operation, and if one of them failures the replacement won’t be immediate, causing damage and loss of production. Using features from substation automation environment, like logic selectivity and interlocks, it’s possible to preserve their health.Here are some pictures that illustrate how these features can be applied.Figure 5. Conveyor motors interlocking according to a traditional fashion.Figure 6. Conveyor motors interlocking using IEC 61850.Figures 5 and 6 show that using IEC 61850 it is possible to switch off motors before overcurrent effects are detected by CTs, lowering the impact on the motors, thus increasing their life cycle. This reduces the chances of damaging windings or more serious problems that would demand replacement and longer maintenance time, resulting in loss of production for longer periods.5 – ConclusionThe availability and the quality of information are assumptions that guide the day-by-day, increasing the level of demand in all areas including the industrial environment, and causing dramatic changes in established practice that are becoming obsolete.With the advent of IEC 61850, more information is collected from the electrical automation system, due to Ethernet communication and data standardization, enabling interoperability, allowing free choice of IED vendors in order to best suit the substation environment. And with such a wealth of data available in supervisory systems, the information integration between automation systems allows multidisciplinary decisions to be taken by putting together the electrical control with process control needs. This provides more efficiency and bigger production availability, current concerns in the competitive global market. Moreover, applications developed typically for electrical environment can be used in process control system, which can be seen in the examples given.In this scenario one can assure the advent of IEC 61850 provided a huge evolution in quality, changing the way we think of automation: automation based on the information integration.6 – ReferencesIEC 61850-SER ed1.0: Communication networks and systems in substations - ALL PARTS; Switzerland: International Electrotechnical Commission, 2010.

2 课程设计内容和要求2.1 设计内容设计并制作一个开关稳压电源。
输入220V交流电,输出30V~36V可调直流电。
通过液晶屏显示。
2.2 设计要求基本要求:(在电阻负载条件下,使电源满足下述要求)1、输出电压U O可调范围:30V~36V;2、最大输出电流I Omax:2A;3、U2从15V变到21V时,电压调整率S U≤2%(I O=2A);4、I O从0变到2A时,负载调整率S I≤5%(U2=18V);5、输出噪声纹波电压峰-峰值U OPP≤1V(U2=18V,U O=36V,I O=2A);6、DC-DC变换器的效率≥70%(U2=18V,U O=36V,I O=2A);发挥部分:1、进一步提高电压调整率,使S U≤0.2%(I O=2A);2、进一步提高负载调整率,使SI≤0.5%(U2=18V);3、提高效率,使效率≥85%(U2=18V,UO=36V,IO=2A);4、能对输出电压进行键盘设定和步进调整,同时显示输出电压电流。
3 设计方案及实现情况3.1 设计方案及论证3.1.1DC-DC主回路拓扑方案一:图1是间接直流变流电路:结构如图1-1所示,可以实现输出端与输入端的隔离,适合于输入电压与输出电压之比远小于或远大于1的情形,但由于采用多次变换,电路中的损耗较大,效率较低,而且结构较为复杂。
图1 间接直流电路方案二: Boost 升压斩波电路:拓扑结构如图1-2所示。
开关的开通和关断受外部PWM 信号控制,电感L 将交替地存储和释放能量,电感L 储能后使电压泵升,而电容C 可将输出电压保持住,输出电压与输入电压的关系为UO=(ton+toff),通过改变PWM 控制信号的占空比可以相应实现输出电压的变化。
该电路采取直接直流变流的方式实现升压,电路结构较为简单,损耗较小,效率较高。
(如图2)图2 boost 升压电路综合比较,我们选择方案二。
3.1.2 控制方案选择方案一:利用PWM 专用芯片产生PWM 控制信号。
此法较易实现,工作较稳定,但不易实现输出电压的键盘设定和步进调整。
方案二:利用KL26单片机产生PWM 控制信号。
让单片机根据反馈信号对PWM 信号做出相应调整以实现稳压输出。
这种方案实现起来较为灵活,可以通过调试针对本身系统做出配套的优化。
但是系统调试比较复杂。
我们选择方案二 。
3.2 工作原理及框图 3.2.1 Boost 升压主电路图3是Boost 升压电路包括驱动电路和Boost 升压基本电路。
电力晶体管(GTR )耐压高、工作频率较低、开关损耗大;电力场效应管(Power MOSFET )开关损耗小、工作频率较高。
从工作频率和降低损耗的角度考虑,选择电力场效应管作为开关管IRF540。
选择ESAD85M-009型肖特基二极管,其导通压降小,通过1 A 电流时仅为0.35V ,并且恢复时间短。
实际使用时为降低导通压降将两个肖特基二极管并联。
ELC U OR LVD(1) 电感值的计算:()22OO IN O INBfU mI U U U L -=其中,m 是脉动电流与平均电流之比取为0.25,开关频率f=20 kHz,输出电压为36V 时,L B =527.48μH ,取530μH 。
电感线径的计算:最大电流I L 为2.5A ,电流密度J 取4 A/mm 2,线径为d,则由L I d J =22*)(π得d=0.892 mm,工作频率为20kHz,需考虑趋肤效应,制作中采取多线并绕方式,既不过流使用,又避免了趋肤效应导致漆包线有效面积的减小。
(2)电容的参数计算:OO IN O O B U f U U U I C ∆-=)( 其中,ΔU O 为负载电压变化量,取20 mV,f=20kHz,U O =36V 时,C B =1465μF,取为2000μF ,实际电路中用多只电容并联实现,减小电容的串联等效电阻(ESR ),起到减小输出电压纹波的作用,更好地实现稳压。
(3)boost 损耗计算:输出电流有效值)(D D I I IN RMS O -⨯⨯=-113.1 代入数据得 I O-RMS =2.069 A而电容的损耗 2/21ESR I P RMS O CO ⨯=-等效串联电阻ESR 取为10 m Ω,代入得P CO1=0.0428 W图 3 主回路3.2.2开机保护电路在直流输入端串联一支保险丝(250V,5A),从而实现过流保护,反接保护功能由二极管和保险丝实现。
用NTC电阻实现了对开机浪涌电流的抑制,当上电瞬间,电阻很大,从而对其防止浪涌电流产生。
(如图4)图4 开机保护电路3.2.3开关管保护电路利用IR2302的欠压保护功能,对其电源电压进行检测,当电压达到200mv 的时候比较器输出高电平,使IR2302的SD管角接高电平,从而使场效应管严格工作在非饱和区或截止区,防止场效应管进入饱和区而损坏,为了防止尖峰电流的产生使芯片误判,我们采用逐波防锁电路。
(如图5)图 5 开关管保护电路3.2.4输出滤波和输出过流保护我们采用电感和电容进行滤波,效果比只使用电容好,我们通过康铜丝采集电流。
当电流超过2.5A的时候打开继电器。
从而关闭电源。
输出端串接电流采样电阻R TEST2,材料选用温漂小的康铜丝。
电压信号需放大后送给单片机进行A/D 采样。
过流故障解除后,系统将自动恢复正常供电状态。
为了降低纹波,采用LC 低通滤波器如图6。
取截止频率f L =200 Hz ,电容取470μF ,由Cf L L 2241π=LCf L π21=代入得L=215.80 μH ,取220μH图 6 过流保护电路3.2.5 KL26主控电路及采集单片机根据电压的设定值和电压反馈信号调整PWM 控制信号的占空比,实现稳压输出,同时,单片机与采样电路相结合,将为系统提供过流保护、过热保护、过压保护等措施,并实现输出电压、输出电流和输入电压的测量和显示。
PWM 信号占空比OIN U U D -≈1 ;当U2=15V ,UO=36V 时,U IN =1.2*U 2-2V=16V , 最大值D MAX =0.556; 当U2=21V ,UO=30V 时,U IN =1.4*U 2-2V=27.4V ,最小值D MIN =0.087系统对于单片机A/D 采样精度的要求:题目中最高的精度要求为0.2%,欲达到这一精度,A/D 精度要达到1/500,即至少为9位A/D ,MP430内置A/D 为12位,只要合理设定测量范围,完全可以达到题目的精度要求。
3.2.6 键盘输入及显示分别通过键盘和LCD 实现数字设定和显示。
键盘用来设定和调整输出电压;输出电压、输出电流和输入电压的量值通过LCD 显示。
3.3 效率分析及计算(U 2=18V,输出电压U O =36V,输出电流I O =2A )DC-DC 电路输入电压U IN =1.2*U 2-2V=19.6V ,信号占空比D ≈1-U IN /U O =0.456, 输入电压有效值I IN =I O /(1-D )=3.676A , 输出功率P O =U O *I O =72 W 下面计算电路中的损耗P 损耗:Boost 电路中电感的损耗:121DCR I P IN DCR ⨯=,其中,DCR 1为电感的直流电阻,取为50 m Ω,代入可得P DCR1=0.68 W Boost 电路中开关管的损耗开关损耗:P SW =0.5*U IN *I IN (t r +t f )*f其中,t r 是开关上升时间,为190ns,t f 是开关下降时间,为110ns,f 是开关频率,为20 kHz,代入可得 P SW =0.2160 W导通损耗))((SNS DSON INC R R ID P +⨯=3.12其中,导通电阻R DSON =77 m Ω,电流感应电阻R SNS 取0.1 Ω,代入得P C =1.23 W 肖特基二极管的损耗流过二极管的电流值与输出电流I 0相等,则二极管损耗D O D V I P =,其中,I O =2 A,取二极管压降V D 为0.35 V ,代入可得P D =0.7 W 两只采样电阻上的总损耗为0.9 W ,综上,电路中的总损耗功率P 损耗=4.5WDC-DC 变换器的效率η= P O /(P O +P 损耗)=94%3.4 硬件电路原理图图7 为整个系统的电路原理图。
